Workflow
Workflow is a generic term for the sequential movement of information or materials from one activity in a process or subprocess to another in the same overall process. As applied in the CBOK, this is the aggregation of activity within a single Business Unit. Activity will be a combination of work from one or more processes. Organization of this work will be around efficiency.
The activities in the workflow will be shown as a flow that describes each activity’s relationship with all the others performed in the Business Unit. Modelling will show this work as a flow that describes each activity’s relationship with all the others performed in the Business Unit.
Workflows can be manual, automated, or more likely a combination of both. Workflow models often include both the diagram and the specific rules that define the flow of information from one activity to the next. When used in conjunction with the workflow system or engine, it usually refers to a software‐based workflow system that will move information from a database to one computer or organization after the other.
